That's because kids don't care. It's the adults that care. My son's friend had a get together when he started middle school to tell his friends that he was born a girl. The kids couldn't care less. My son was like, whatever. We had never discussed LGBTQ issues with him, so he had no influence from us.It may just be a generational thing. A female to male trans athlete in my middle school would have been teased relentlessly.
30 years later, when I coached a trans kid on a boys middle school team, it was not at all an issue. I don’t think a single kid cared one way or the other. The only time it came up was a uniform question about t-shirts under their tank tops.
I'm pro LGBTQ rights but some of it goes too far for me personally, like the whole pro-noun thing, non-binary and identifying as an animal. The whole Bruce Jenner thing makes me go, huh? I think that's just human nature and not some inherent homophobia.
If you haven't seen it, check out the latest Chappelle standup. He does a bit on the different groups in LGBTQ going on a road trip together. It's hilarious.
